Unbound is so much of a crap shoot on tires that I don’t read too much into it. But durability is still a question mark for me. All the testing I’ve seen is that the new Dub 2.2 isn’t any faster than the 2.2 Race King, so I went ahead and bought up some extra race kings that I’ll use at chunky races like Big Sugar, Rule of 3, and Unbound for the next couple years. Maybe the new dub will eventually prove as durable (or more), but I’m kind of hedging my bet and there isn’t much downside unless the tests are underestimating the speed of the new dub. I do plan to ride the new 2.4 dub at leadville if it holds up in testing, but leadville isn’t much of a durability test (knock on wood).

Rosa Klöser ran 2.2 Dubs, and also experienced a flat. Of course she was still in the mix for third place until she spaced out and took a wrong turn into the finishing chute and ended up fourth. Of course, any tire can flat, at Unbound. For races like this the best bet is likely to try and do your best with line choice to avoid flats in the chunky/sharp sections, so maybe you have to be a little conservative with your drafting in these sections, and allow a little bit of a gap.

This seems perhaps premature, but wrt Continental tires; are Rapid/Grip compounds a downgrade from Black Chili?
I suspect many more people were on 2.2 Dubnitals this year than 2.2 Race Kings last year - but even then the reports don’t seem to be positive. Lots of punctures and cut tires.
In a similar aspect, I have seen more punctures on the ‘new’ pathfinder pro’s that I would expect. I actually purchased a 40mm for a backup mud tire for unbound but after seeing enough reviews of punctures, I returned it.
Maybe it will gain a better reputation over time, but what I’ve seen so far leaves me a bit skeptical.

Impressive. As the BRR article noted, this tire is a lot different to the G-One Speed they tested previously in the smaller 40mm width. That previous 40mm G-One Speed had a carcass thickness at the centre that was almost twice as thick as this latest 60mm Pro variant (3.1 mm versus 1.6 mm). That probably goes a long way towards explaining the huge difference in rolling resistance numbers between those two variants, which look identical from the tread patterns.
Indeed this 60mm G-One Speed pro is more similar to the old Liteskin Big One from 2016, which isn’t so easy to find nowadays on BRR.

It seems like this could be crazy fast on the right terrain. Some hard packed down smooth and/or sandy gravel with no rocks. Maybe some rails to trails type terrain.
It seems it would likely get ripped to shreds on anything with sharper rocks/stones.

Mental results, really interesting tire. Very tempted to slap a pair on my hardtail just for the funzies.
I foresee a lot of these on drop bar converted MTBs
Friend of mine had a pair of those gone speed pros, they were fast but handling was not good and punctures was also a problem.
I would love it if at my next race loads of people are running these.

I have been running the G-One Pro’s on my beach race bike (the tire is actually designed specifically for beach racing). But the bike also doubles as my winter training bike, so lots of road miles and easy gravel trails (no big rocks). Currently about 3000km on them and no flats yet.
The tires are really fun and fast on gravel (a bit sketchy but fun). But I don’t think they would survive actual gravel racing were you are hitting stuff blind.

Jesus wept 9.8 at 35psi? That’s faster than most road race tyres 
.
Probably as puncture resistant as riding on a kids party balloon but for a fat tyre crit…
No need to speculate about it’s puncture resistance, BRR also tests for that and the results are quite acceptable for the G One Speed Pro. Even better sidewall result than a Peyote, same value as a Rock XC, and thread not that far off a Rick

Wonder what kind of mileage it can do. Would make a hardtail real fun.
Well, on the Schwalbe direction I’ve got a set of the G One Speed Pro 2.35 on the way to test and just wrapped up a test round on the G One RX Pro 700 x 50 today.
Fastest gravel tire on gravel I’ve seen so far.

Perfect timing. Needing a new front to replace my trusty Pathfinder and was about to pull the trigger on rx pro today! The 45s are on sale at Excel. Was hoping for a 50 for my older Revolt, but 45 will do.
Edit: I have a ton of biketiresdirect bucks, so going there and doing the cam jones with 50 front, 45 rear

Are the tan walls schwalbes worse than the black like with other brands? (Conti, tufo)
I think they fairly even but I have no data or science to back that up.
I got my rx pros today. Mounted. Of course one came with the most tiniest of pin holes in the sidewall where the tan sidewall meets the black tread. Sealant should fill it, but def trying to get a free tire from BikeTiresDirect out of this.
edit: according to Schwable and BTD this is normal.
edit #2: The 45 blew up to 45’ish. The 50 is takin it’s time to blow up to 50. Been sitting at 46/47 for a bit.
Also, previous gen (2020’ish) Revolt, I think a 2.1 would fit in the fork for dry conditions pretty easily. A 50 rear would work for dry as well.
What internal rim width?
For the time being, I’m running my older Hunt Aero 50s I pulled off my road bike since that got new hoops. 20 I think.
Pathfinder 42s blew up to 42 on these rims.
